[SOLVED] Kernel Question GNU/Linux Fedora 17 x64

view story

http://forums.fedoraforum.org – Since i have Fedora 17, the system updated the kernel several times. Now when i boot, the GRUB boot loader shows 3 different kernels. 3.3.. 3.2.. and 3.1... it boots from the newest 3.3.. like it should. But now i ask myself, does this harm the system to have 3 different kernels ? I dont know about that because im kind of new to kernels and stuff. Would it harm anything on the system if i would remove the 2 older kernels ? And if yes, what ? If no, how can i do that ? Thank you very much ! (HowTos)
